cscθ cosθ = -1
1/sinθ cosθ = -1
cosθ/sinθ = -1
as with any angle,
cos^2θ + sin^2θ = 1
In this case,
cosθ = -sinθ
tanθ = -1
θ = 3π/4 or 7π/4
No idea at all? Hmmm. I cannot believe that the question was assigned, yet the material never taught!!!???
And have you never heard of google?
An angle θ satisfies the relation csc θ cos θ = -1.
A) Use the definition of the reciprocal trigonometric ratios to express the left side in terms of sin θ and cos θ.
B) What is the relation between sin θ and cos θ for this angle?
C) Determine two possible values for θ.
- Please help me with this question, I have no clue where to start as my teacher never taught us something like this!
